Juergen Reis is MBL's chief engineer, which means he's the man behind every product from MBL from DACs, to Players, to Preamps, to Amps, to the ever enticing MBL Radialstrahler speakers. I first read Juergen's following remarks on another website where he posted them as a series of comments in response to a discussion about "USB tweaks" and the notion that what cannot be measured cannot make a sonic difference.

As with much of what Juergen says and writes, I found his comments very interesting, informative, and relevant to some of the discussions that have taken place here on AudioStream and elsewhere on the web. With that in mind, I asked Juergen if I could publish them here, in a more finished form, and he very graciously said...yes. Enjoy!

Editor's Note: The following piece was written by Jason Stoddard of Schiit Audio as Chapter 5 of his ongoing work Schiit Happened: The Story of the World's Most Improbable Start-Up, which I highly recommend reading in its entirety. "The Subjectivist/Objectivist Synthesis" struck me as being relevant to many discussions we have here on AudioStream shedding much needed light on the middle ground. Jason was kind enough to allow me to publish it here in its entirety. Enjoy!

Editor's Note: iFi submitted the following technical paper in response to Steve Plaskin's review of the iFi Audio micro - iUSB 3.0 (see review). I've elected to publish it separately since it stands on its own and is well worth highlighting.

Schiit Audio is well-known among audiophiles as a company that delivers well-liked, well-loved?, products at affordable prices. Mike Moffat along with Jason Stoddard are the men behind Schiit, each having a long and storied hi-fi history. Mike Moffat generously agreed to take part in this Q&A, which I hope will give you a better understanding of the company's products and their attitude, which is anything but...

AURALiC caused quite a splash with their Vega DAC which I reviewed very favorably (see review) as did John Atkinson in Stereophile (see review). I continue to use the Vega as my reference. AURALiC introduced a new product, the ARIES, at CES 2014 and it again had the crowds buzzing mainly with its ability to stream DSD over wi-fi. I received a review unit about a month ago and have been working through iterations of the Lightning DS app which controls the ARIES as well as a few firmware upgrades.

Michal at Mytek R&D Studio in Brooklyn, testing the new DSD ADC prototype circuit (June 2014)

I first met Mytek's Michal Jurewicz at RMAF 2011. This event marked the official launch of AudioStream as well as the debut of Mytek's first consumer DAC. At that time, the Mytek Stereo192-DSD DAC at $1695 represented the least expensive DSD-capable DAC by a good margin and remains, imo, very competitive in terms of its price and performance. Michal was kind enough to participate in this Q&A where we focus on DSD, misconceptions, and Mytek's place in the world of hi-fi.

Qobuz Co-Founders Yves Reisel (left) and Alexandre Leforestier

France-based Qobuz (pronounced cow-buzz and named after a traditional two-stringed instrument of Central Asia) is one of the premier online music retailers of CD-quality and high resolutions downloads. Qobuz is also one of the first sites to offer a CD-quality streaming service, if not the first, and in my opinion it is also the most advanced website for music download sales and streaming services around. One peak at their home page on any given day will tell a lot of what you need to know—podcasts, blogs, hi-fi, editorials, and more, Qobuz embodies many of the best qualities of online sales combined with a healthy human touch. Yves Riesel, Qobuz's Co-founder and CEO, was kind enough to agree to this Q&A and I'd like to thank him for his time and answers.

I just came across this short, 2-minute+ video sponsored by the Audio Engineering Society (AES) from 2000 and found it very interesting and relevant, especially in view of all the anti-Pono talk of late. Watch the video and see if you agree.

I recently completed my reviews of the full suite of Bluesound products including the Vault (see review), the Powernode/Duo (see review), Node (see review), and Pulse (see review). I was impressed with the lot, finding the Bluesound products mature beyond their years in terms of both the user friendly interface and overall sound quality. I had an opportunity to ask Bluesound's Chief Brand Officer, John Banks, some questions about Bluesound to hopefully get a better picture of this new company.

AudioQuest shared their White Paper, "Evaluation of Digital Devices and Proper Warm-Up for Ideal Listening and Measurements" and I thought it well worth sharing with AudioStream readers. While you can pretty much surmise the gist of the white paper from its title, you may be surprised at the conclusions drawn from measured results. Enjoy.

Thorsten Loesch

Most readers are familiar with iFi Audio whose affordable products include DACs, portable headphone amps, a USB power supply, Tube Buffer/Pre-Amplifier, and more. We've reviewed a number of their products including the iFi iDAC (see review), the iUSBPower (see review), and the iTube Active Tube Buffer/Preamp (see review). Abbington Music Research (AMR) also produces a full line of "Reference Class" products including amplifiers, preamplifiers, loudspeakers, disc players, DACs, and more. The Chief Designer behind both product lines, Thorsten Loesch, was kind enough to participate in this Q&A with AudioStream where we dig into some of the nitty gritty behind PCM versus DSD, human hearing, the joy of vacuum tubes, and more. I'd like to thank Thorsten for the time and effort he put into his response and I hope you enjoy it as much as I did.

It should come as no surprise at this point that Neil Young was at SXSW to talk about Pono. I had the opportunity to spend some time talking to Neil Young about his new venture.

Jitter. Its a controversial subject among audiophiles (what isn't?). PS Audio has posted Part 2 of their Jitter video series with "consulting digital expert" Ted Smith, "Audible Effects of Jitter", but I've included Part 1 here which is titled "Why Jitter Matters" just in case you missed it. Part 2 will start directly after (duck and cover!).

In this third installment I will cover possible methods by which bit perfect software can affect sound quality in a DAC.

I think its fair to say that Charlie Hansen, Ayre's Founder and Designer, is not exactly a fan of DSD. Thankfully, that didn't stop him from offering DSD-capable versions of Ayre's QB-9, DX-5-DSD, and now the QA-9 thanks to AlpineSoft's VinylStudio DoP vinyl ripping software. What the guys at Ayre have gone and done is ripped parts of three tracks to single-rate DSD and 24/192 using the QA-9 so we can compare DSD to PCM. But there's more...
